An object of the present invention is to provide a microorganism that efficiently produces EPA and a method for producing EPA using the microorganism. The present invention relates to a microorganism having an ability to produce docosahexaenoic acid (DHA), wherein the microorganism contains a protein composed of an amino acid sequence in which at least one of the amino acid residues at positions 6, 65, 230, 231, and 275 in the amino acid sequence represented by SEQ ID NO: 2 has been substituted with another amino acid residue (mutated OrfB), and is capable of producing eicosapentaenoic acid (EPA), and the like.

Provided herein are compositions, systems, and methods for delivering an effector protein into a cell. The present disclosure, in some aspects, provide novel proteins delivering an effector protein into a cell. The novel proteins are supernegatively charged proteins derived from highly anionic proteins identified from the proteome (e.g., human proteome). The novel protein tags can be associated (e.g., covalently or nocovalently) with the protein to be delivered to facilitate delivery of the effector protein into a cell.

The present invention provides isolated FAD2, FAD3, FAB1 and FAE1 genes and FAD2, FAD3, FAB1 and FAE1 protein sequences of Camelina species, e.g., Camelina sativa, mutations in Camelina FAD2, FAD3, FAB1 and FAE1 genes, and methods of using the same. In addition, methods of altering Camelina seed composition and/or improving Camelina seed oil quality are disclosed. Furthermore, methods of breeding Camelina cultivars to produce plants having altered or improved seed oil and/or meal quality are provided.

Microalgal mutant to produce high-value essential LCPUFA oils including eicosadienoic acid (EDA), dihomo-γ-linoleic acid (DGLA), arachidonic acid (ARA), and eicosapentaenoic acid (EPA) in various ratios in are provided.

A method for biosynthesis polyhydroxybutyrate by a yeast transformant of the invention includes the following steps: (1) transforming a polyhydroxybutyrate biosynthesis related gene into an oleaginous yeast to obtain an yeast transformant. (2) screening the yeast transformant. (3) cultivating the yeast transformant to obtain the polyhydroxybutyrate. The method of the invention provides a way of cheaper, faster and flexibility in biotechnology metabolism to improve PHB production.

The present invention provides a method of synthesizing celosianin II, a method of synthesizing a betaxanthin, an amyloid-β polymerization inhibitor or a therapeutic or preventive agent for Alzheimer's, an amyloid peptide aggregation inhibitor, and an HIV-1 protease activity inhibitor. A gene having a celosianin II synthesis ability has been isolated from quinoa, and a method of synthesizing celosianin II of the present invention has been constructed. Besides, it has been recognized that celosianin II or the like serves as an active ingredient of each of an amyloid-β polymerization inhibitor or a therapeutic or preventive agent for Alzheimer's, an amyloid peptide aggregation inhibitor, and an HIV-1 protease activity inhibitor.

The present disclosure is related to genetically engineered microbial strains and related bioprocesses for the production of products from acetyl-CoA. Specifically, the use of dynamically controlled synthetic metabolic valves to reduce the activity of certain enzymes, leads to increased product production in a two-stage process.

The present invention is related to a novel enzymatic process for production of retinoids via a multi-step process, which process includes the use of heterologous enzymes having activity in a carotene-producing host cell, particularly wherein such process results in high percentage of retinoids, in trans-isoform.

The present disclosure relates to genetically engineered host cells and methods of producing a lipid-derived compound by employing such host cells. In particular embodiments, the host cell includes a first mutant gene encoding a cytoplasmic tRNA thiolation protein. Optionally, the host cell can include other mutant genes for decreasing fatty alcohol catabolism, decreasing re-importation of secreted fatty alcohol, or displaying other useful characteristics, as described herein.

Provided herein are methods for generating cellular biomass in continuous aerobic fermentation systems. The biomass yield, and the concentration of polyhydroxyalkanoate within the biomass, are each directed to advantageous levels by operating the continuous fermentation system under particular nutrient limitation conditions. Also provided are biomass produced using the provided methods, and animal feed compositions including the provided biomass.
